摘要
Abstract
1,1,1-tri- (p-hydroxyphenyl) ethane(THPE) was first prepared from acetylacetone and phenol under the acidic condition and then purified. It was also characterized by DSC, FT-IR, and liquid chromatography. The results showed that the optimum conditions for its synthesis, under which the yield of the crude THPE was 74%, were as fallows: the molar ratio of phenol and acetylacetone was 8:1; the consumption of catalyst (concentrated sulphuric acid) and the cocatalyst (sulphur propionic acid) was 6% and 2.1% respectively of the mass of phenol;the reaction temperature was 50 'C. The purity of THPE can reach 99.52% after three times purifications.关键词
